Altered Left ventricular (LV) diastolic filling has been shown in subjects
with hypertension. Age is a major determinant of Doppler indexes of LV dias
tolic filling; therefore, a group of subjects of uniform age should prefera
bly be chosen, if other determinants of diastolic LV filling are to be stud
ied. A limited body of data is available regarding Doppler indexes of LV fi
lling in hypertensive persons of a similar age. We therefore evaluated 26 h
ypertensive subjects (13 women, and 13 men) 50 years old by Doppler echocar
diography. The peak, velocity of early diastolic filling (E wave), the peak
velocity of atrial filling (A wave), the early-to-atrial peak velocity (EI
A) ratio, and the deceleration time of early velocity were measured. The pe
ak E wave velocity was 0.76 +/- 0.11 versus 0.62 +/- 0.13 m/s (P < 0.005),
and the EIA ratio was 1.11 +/- 0.24 versus 0.93 +/- 0.23 (P < 0.05) in hype
rtensive women and men, respectively. The peak A wave velocity was increase
d and the EIA ratio was decreased in both hypertensive women and men compar
ed with healthy 50-year-old subjects. In multivariate analyses, LV diameter
, body mass index, and gender correlated with the EIA ratio in hypertensive
persons. It is concluded that there is a significant difference in. Dopple
r LV filling indexes between 50-year-old hypertensive women and men. LV dia
meter, gender, and body mass index are independent determinants of LV diast
olic inflow in similarly aged hypertensive persons.
